Fix fullscreen/unfullscreen not handle correctly when trigger by wind…

…ow manager

Expect handling from accel-key fullscreen toggle, also handle from window state changed.

Because if you bind same accel-key for fullscreen in window manager, you will not trigger it
from Guake toggle fullscreen, instead from wm.

This should fix wierd window size & position when first using Guake fullscreen toggle, then
toggle fullscreen by wm hotkey.
